15 players times the uniforms(x) and the cost of the ball equals the total spent 15(x+8)=435
Answer:
She donated b/50 books
Step-by-step explanation:
In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:
The total number of books/ the total number of students.
The average number of books is this b/150.
Now, we are also told that Hannah donated 3 times the average number of books.
This is simply calculated by multiplying the average number of books donated by 3
This is equal to 3 * b/150 = b/50 books
Hence, Hannah donated b/650 books
Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19

Hello!</h2>
The answer is:
The x-coordinate of the solution to the system of equations is:
<h2>
Why?</h2>
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:
Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:
Now, substituting "y" into the first equation, to isolate "x" we have:
Hence we have that the x-coordinate of the solution to the system of equations is
Have a nice day!
